With vaccination indicators Among American preschoolers, it has been constantly falling in recent years, and the Secretary of Health and Social Welfare Robert F. Kennedy Jr. Honesting of recruitment in childhood vaccination, measles and other previously eliminated infectious diseases may become more common. AND New analysis Published today by epidemiologists at Stanford University, they are trying to estimate these effects.
Using the computer model, the authors found that with the current vaccination rates at the level of measles vaccination, it can be restored and become consistently present in the United States in the next two decades. Their model predicted this result in 83 percent of the simulation. If the current vaccination indicators remain the same, the model estimated that the US could see over 850,000 cases, 170,000 hospitalization and 2,500 deaths in the next 25 years. The results appear in the Journal of the American Medical Association.
“I do not consider it speculative. This is a model exercise, but it is based on good numbers,” says Jeffrey Griffiths, a professor of public health and social medicine at Tufts University School of Medicine in Boston, who was not involved in the study. “The most important thing is that Odra is very likely that it will quickly become endemic if we are in this way.”
The United States declared the Odra eliminated in 2000 after decades of successful vaccination campaigns. Elimination means that there was no chain of transferring diseases lasting longer than 12 months in the country. However, the current explosion of the Oder in Texas may violate this status. With over 600 cases, 64 hospitalizations and two deaths, this is the biggest explosion he has seen since 1992, when 990 cases were associated with one explosion. The US saw throughout the country 800 cases of measles so far in 2025.Most since 2019. There were 285 cases last year.
“We are really at a point where we should try to increase vaccination as much as possible,” says Mathew Kiang, an assistant professor of epidemiology and population health at Stanford University and one of the authors of the article.
Childhood vaccinations in the USA were down. Data collected by the Centers for Disease Control and Prevention based on state and local vaccination programs have shown that from the 2019-2020 school year to the 2022-2023 school year, relations among preschoolers fell from 95 percent to about 93 percent. These vaccines included MMR (measles, pig and rubella), DTAP (diphtheria, tetanus and cunning chicken), polio and chickenpox.
In the current study, Kiang and his colleagues modeled each condition separately, taking into account their vaccination rates, which ranged from 88 to 96 percent for the Oder, 78 percent to 91 percent for the diphtheria and 90 to 97 percent for Polio vaccination. Other variables included the demographic data of the population, the effectiveness of the vaccine, the risk of importing the disease, the typical duration of the infection, the time between the exposure and the possibility of spreading the disease, and the contribution of the disease, also known as the basic number of reproductions. Odra is highly contagious, with one person can infect from 12 to 18 people. Scientists used 12 as the basic number of reproductions in their study.
